The Medical Exclusion of an Immigrant to the United States of America in the Early Twentieth Century. The Case of Cristina Imparato.
The medical inspection of immigrants arriving in the United States in the late nineteenth and early twentieth centuries was framed by a need to rapidly process large numbers of people. Scientific […]
An Uncertain Dominion: Irish Psychiatry, Methadone, and the Treatment of Opiate Abuse.
This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland […]
Preparation and antibacterial characteristic of water-insoluble antibacterial material QPEI/SiO(2).
Polyethyleneimine (PEI) was grafted onto micron-sized silica gel particles via the coupling action of gamma-chloropropyl trimethoxy silane, and grafting particles PEI/SiO(2) was prepared. Then, polymeric reactions of two steps, tertiary amination reaction and quaterisation, were conducted for the grafted PEI. After quaterisation of the […]
A novel amphiphilic nano hydrogel using ketene based polyester with polyacrylamide for controlled drug delivery system.
A ketene based Low molecular weight polymer (LMKP) having ester functional group was prepared using glycine through surface initiated anionic polymerization. NMR, ATR-FTIR & SEC were used to characterize the LMKP. The LMKP and acrylamide (AAm) were […]
Dental casting alloys behaviour during power toothbrushing with toothpastes of various abrasivities. Part II: corrosion and ion release.
The purpose of this study was to evaluate the long term effect of abrasivity of toothpastes normally used over the corrosion behavior and ion release of the different dental casting alloys. Three dental casting alloys […]
Dental casting alloys behaviour during power toothbrushing with toothpastes with various abrasivities. Part I: wear behavior.
The purpose of this study was to evaluate the long term effect of abrasivity of toothpastes normally used over the surface and mechanical properties of dental casting alloys. Three dental casting alloys (Ni-Cr, Co-Cr, c.p. Ti) and […]
Preparation of hydroxyapatite spheres with an internal cavity as a scaffold for hard tissue regeneration.
Microparticulates are currently regarded as a useful matrix for the delivery of bioactive molecules and tissue cells. Herein, hydroxyapatite (HA) spherical microparticulates with an internal cavity were produced using an oil-in-water emulsion technique. The HA slurry in the […]
Biodistribution of titanium dioxide from biologic compartments.
The layer of titanium dioxide (TiO(2)) of the implant is chronically exposed to the internal electrolyte milieu in the peri-implant biological compartment. Corrosion results from electrochemical attack and ensuing gradual degradation of the metallic materials and is thus of biological interest when these biomaterials are employed […]
The interaction of zinc oxide-based dental cements with aqueous solutions of potassium fluoride.
The ability of zinc oxide-based dental cements (zinc phosphate and zinc polycarboxylate) to take up fluoride from aqueous solution has been studied. Only zinc phosphate cement was found to take up any measurable fluoride after 5 h exposure to the […]
A novel COL3A1 gene mutation in patient with aortic dissected aneurysm and cervical artery dissections.
A considerable proportion of aortic aneurysms are shown to have genetic backgrounds. The COL3A1 gene, which encodes type III procollagen and causes Ehlers-Danlos syndrome (EDS) type IV, is one of the candidate genes associated with aortic aneurysms. The […]
